Think twice the next time you play a videogame or surf the Net: ‘Internet-use disorder’ is set to be added to the list of mental illnesses in the worldwide psychiatric manual. Kids are identified as being especially at risk.

The international mental health encyclopedia known as the ‘Diagnostic and Statistical Manual of Mental Disorders’ (DSM-IV) will include Internet-use disorder as a condition “recommended for further study” in its forthcoming May 2013 edition.

Psychologists believe that Internet addiction should be categorized like other addiction disorders as it has similar symptoms, including emotional shutdown, lack of concentration and withdrawal.
